Title: Flexible corrosion-resistant conduit and method
Inventor: HEIMANN ROBERT L
IPC: B29C47/06
Filed: 1990-12-18
Abstract: FLEXIBLE CORROSION-RESISTANT CONDUIT AND METHOD            Abstract A flexible non-metallic, corrosion-resistant conduit for a cable assembly which includes an extruded tubular synthetic plastic liner portion having on is outer surface a plurality of circumferentially spaced helical strengthening ribs, and an extruded tubular synthetic plastic sleeve portion extending concentrically about the liner portion.  According to the method of the present invention, as the liner portion is extruded via a first die, it is longitudinally pulled and rotatably twisted about its longitudinal axis to impart the desired helical configuration to the ribs.  In one embodiment, the sleeve portion is extruded by a second die concentrically about the liner, thereby to fill the spaces between the ribs, and in a second embodiment, the sleeve portion is simultaneously formed by the first die integrally with the tips of the ribs, thereby to define helical passages between the ribs.  According to a third embodiment, an intermediate synthetic plastic layer is extruded on the liner prior to the formation of the sleeve, and in a fourth embodiment, at least one reinforcing filament layer is wound on the liner prior to the formation of the intermediate layer.

IPC: G05D16/06
Filed: 1991-06-03
Abstract: ABSTRACT OF THE DISCLOSURE     A valve assembly for fluid pressure regulation provides freedom from static pressure creep by eliminating distortions and stresses normally introduced to valve parts during assembly of the regulator.  A floating valve seat permits normal installation of a valve housing in the regulator body with no transfer of stress or distortion to the valve seat. Thus static pressure creep, normally attributable to micro distortions of the valve seat, is avoided.  Options are also provided to install the floating valve seat directly in a regulator body without the valve housing.

Title: Integrated heating, cooling and ventilation system
Inventor: ALLEN GREGORY A S
IPC: F24D11/02
Filed: 1991-06-12
Abstract: ABSTRACT           The system uses heat pump technology and a phase-change thermal storage tank to supply space heating, space cooling, and domestic hot water to a building.  A heat exchanger in the exhaust air stream and another one attached to the building grey water drain pipe extract heat from the stale air and grey water for delivery to the thermal storage tank.  Subsequently, this heat is extracted from the thermal storage tank to supply the evaporator in the heat pump when a heating demand occurs, to supply hot water for occupant use and space heating when required.   The system, in a single package, physically and thermally integrates space heating and cooling, ventilation, and hot water supply.  Cooling is supplied via a chilled liquid loop circulating via the thermal storage tank.  Heating/cooling is supplied via a fan coil while a smaller fan coil exhausts continuously to outside, providing central ventilation from kitchens and bathrooms.

Abstract: ABSTRACT     The improved process for producing a signature panel comprises the steps of forming on the writing surface of a panel substrate a printed graphic pattern that will change upon exposure to alcohols, organic solvents, bleaching agents and surfactants, and laminating the other surface of the panel substrate with a thermoplastic resin by extrusion, or hot melt coating.  According to this process, signature panels can be thermocompressed at comparatively Low temperatures not only to roll mills of overprint cards using a polyvinyl chloride sheet as an oversheet base but also to card substrates such as PET sheets, metal sheets and glass sheets without causing any adverse effects on the graphic pattern printed on the writing surface of the panel which will change upon exposure to chemicals.

Title: Anaerobic digester
Inventor: JORDAN JEFF P
IPC: C02F11/04
Filed: 1991-09-25
Abstract: ANAEROBIC DIGESTER      Abstract An anaerobic digester for digesting animal manure and other biologically degradable material contains support media for enhancing the contact between the microbes in the digesting mass and the available nutrients. The digester includes a novel fluid circulation and distribution system. The distribution system prevents build up of heavy material in the bottom of the digester and prevents agglomeration of light material at the top of the digester. The digesting fluid travels over a floating weir into an intake and impeller assembly. The impeller drives the fluid through a conduit located adjacent the floor of the digester. Nozzles in the conduit project the fluid downwardly toward the floor thus causing a sweeping action on the floor. Fluid then flows upwardly past the support media. Risers are provided at the ends of the conduit, which terminate in nozzles at the surface of the digesting liquid. The nozzles direct the flow of digestingmaterial back toward the fluid inlet and also sweep the corners of the digester to prevent material accumulation.     LEJ/gfb

Title: Determining the rate at which material is received by an extruder from a feed container
Inventor: SAATKAMP RICHARD
IPC: B29C48/08
Filed: 1992-02-18
Abstract: A method of determining the rate at which plastic granules are received by an extruder from a feed container having an outlet which opens into the inlet of the extruder. In which method granules are continuously fed to a supply container and consecutive charges of granules are intermittently fed to the feed container. The feed container is weighed before or at the beginning of or after or at the end of its filling operation. The time required to withdraw the material in the amount which has been determined by the weighing operations is measured, and the flow rate of the material is calculated from the amounts of material which have been received from the feed container in the measured intervals of time. A uniform feeding of material into the extruder will be ensured if granules and marginal strip material are supplied to the cyclone like container. The supply container is substantially used only as a mixing container and opens into a charge-holding container, which is provided between the supply container and the feed container. The granules of at least one component thereof and recycled marginal strips are continuously fed to the supply container. The feed container and the charge-holding container are weighed in intervals of time, and the feed rate of the granules of the at least one component is correspondingly increased or reduced when the measured total weight of the feed container and of the charge-holding container differs from a predetermined desired weight.
